A 27-year-old man believed to be the head of a large drug-trafficking ring pled guilty to multiple felonies today as part of an agreement in which the defendant will accept a sentence of life in prison.

Oscar Cavadas was among 14 people charged after officers with the Southern Nevada Drug Task Force seized more than 200 pounds of methamphetamine, $300,000 in cash and 11 vehicles in July 2011.

“A lot of hard work by a lot of great law enforcement partners took a massive amount of narcotics off the streets,” District Attorney Steven Wolfson said. “This was the largest methamphetamine bust ever in Southern Nevada, and now Mr. Cavadas will get an equally serious prison term.”

Cavadas pled guilty today to trafficking in controlled substances, unlawful possession of a firearm and conspiracy to violate the uniform controlled substances act. Cavadas and prosecutors have agreed that Cavadas will accept a sentence of life in prison for the trafficking charge when he is formally sentenced in February. This sentence typically allows for the defendant to be eligible for parole after 10 years. As part of the plea deal, prosecutors agreed to ask that Cavadas be eligible for parole after nine years. Also, prosecutors agreed to ask that the sentences for the other two charges run concurrently with the life sentence.

The Southern Nevada Drug Task Force, which includes officers from the Las Vegas Metropolitan Police Department, Henderson, North Las Vegas, the U.S. Drug Enforcement Agency, U.S. Immigration and Customs Enforcement, and the District Attorney’s Office spent more than a year investigating the drug-trafficking organization headed by Cavadas. Two of the 14 people charged in connection with the drug ring are still at large. The other 12, including Cavadas, have all pled guilty to various drug-related felonies.
